Firefox 4.0 is now available for download for Windows and Mac. It’s not yet available on the official Firefox website, but you can grab the latest Firefox 4.0 release from the Mozilla FTP. It will be announced later today.

The latest Firefox 4.0 brings a variety of new features, impr0vments and enhancements to the browser. Afterall, we all expect something really good from Mozilla as this Firefox update took months in development.
